Abstract
(EN)
Disclosed is a power converter having a semiconductor switching element, wherein an applied voltage suppressing circuit that eliminates a voltage breakdown of the semiconductor switching element is reliably mounted, and a set voltage of the semiconductor switching element can be inspected without breaking the IC and the like in the peripheral circuits. In the power converter having the semiconductor switching element (3), the applied voltage suppressing circuit (15) that suppresses the voltage applied to the semiconductor switching element (3), and at least one component, i.e., the component of a drive circuit (13), without which the semiconductor switching element (3) turns off, are transferred to and disposed on a sub-substrate (16) (separate unit), which is separately configured from a main substrate having mounted thereon the semiconductor switching element (3), the drive circuit (13), a control circuit and the like, and which is electrically connected to the main substrate.

L'invention concerne un convertisseur de puissance, dans lequel, un circuit de suppression de tension appliquée permet d'empêcher une tension de claquage de l'élément de commutation à semi-conducteurs, tout en permettant l'inspection d'une tension prédéterminée de l'élément de commutation à semi-conducteurs sans disjonction d'un circuit intégré (CI) ou similaire dans les circuits périphériques. Ce convertisseur de puissance possédant un élément de commutation à semi-conducteurs (3), présente une structure selon laquelle il est séparé du substrat principal sur lequel sont montés l'élément de commutation à semi-conducteurs (3), un circuit d'excitation (13), un circuit de commande et similaire, et le circuit de suppression de tension appliquée (15) empêchant une tension de claquage de l'élément de commutation à semi-conducteurs (3) ainsi qu'au moins une pièce qui est une pièce structurelle du circuit d'excitation (13), et sans laquelle l'élément de commutation à semi-conducteurs (3) est mis à l'arrêt, sont transférés et montés sur un substrat secondaire (16) (unité séparée) relié électriquement.
